Chemical Structure
Description
Structurally, 3-(2-([1,1'-biphenyl]-4-yl)imidazo[1,2-a]pyridin-3-yl)acrylic acid (C22H16N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 340.37 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
3-(2-([1,1'-biphenyl]-4-yl)imidazo[1,2-a]pyridin-3-yl)acrylic acid (CAS 727652-23-5) is a high-purity analytical reference standard with the molecular formula C22H16N2O2 and a molecular weight of 340.37 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
